The current approach to reducing impact forces during component placement in micro-assembly is to couple the gripper with 5 Degrees Of Freedom (DOF) to the drive unit of the placement device, wherein the mass of the gripper has been reduced maximally. At the end of the placement motion the drive unit will move relatively to the gripper, as linear as possible given the limitations of the constru...

Grasping mechanisms (grippers) are used for a wide range of applications including fixturing arrangements, industrial, agricultural, and service robotics for medical and home use. The gripper must immobilize the object it is manipulating , while applying the minimal necessary grasping force, in order to prevent the grasped object's bruising. Performing grasp analysis and synthesis, requires the...

Highlights A robotic mushroom picking mechanism was developed, including positioning, picking, and stipe trimming. The end-effector designed based on a bending motion around the stipe-substrate joint. overall success rate of developed reached 91.4%. Acting time air pressure for suction cup were studied in bruise level tests. Abstract . Button (Agaricus bisporus) harvesting mainly relies costly ...

dria to provide a stable intracellular niche for replication (Luhrmann and Roy, 2007). The pathogen also activates Akt and Erk1/2 signaling to promote survival (Voth and Heinzen, 2009). Each of these events relies on Coxiella protein synthesis, suggesting the organism secretes a distinct effector(s) to regulate apoptosis. Unfortunately, effector identification and characterization has been hamp...

Telepresence systems can be used for repair and maintenance in environments that are hard to access or dangerous for the human. Current systems can effectively the gross motor skills of the human operator into actions in the remote environment. In comparison, fine manipulation, like the secure grasping and handling of complex objects, is error-prone and strenuous for the operator. To execute su...

Human CD8+ memory- and effector-type T cells are poorly defined. We show here that, next to a naive compartment, two discrete primed subpopulations can be found within the circulating human CD8+ T cell subset. First, CD45RA-CD45R0(+) cells are reminiscent of memory-type T cells in that they express elevated levels of CD95 (Fas) and the integrin family members CD11a, CD18, CD29, CD49d, and CD49e...

Wepropose a novel state estimator for legged robots, STEP, achieved through preintegrated foot velocity factor. In the factor, usual non-slip assumption is not adopted. Instead, end effector becomes observable by exploiting body speed obtained from stereo camera. other words, effector’s pose can be estimated. Another advantage of our approach that it eliminates necessity contact d...

Human CD8 1 memoryand effector-type T cells are poorly defined. We show here that, next to a naive compartment, two discrete primed subpopulations can be found within the circulating human CD8 1 T cell subset. First, CD45RA 2 CD45R0 1 cells are reminiscent of memorytype T cells in that they express elevated levels of CD95 (Fas) and the integrin family members CD11a, CD18, CD29, CD49d, and CD49e...

This paper presented the designing and building of a robotic gripper with five degrees of freedom capable to perform cylindrical grasp and grasp by terminal opposition of the human hand. The gripper has a pressure sensorial system, where each link has a sensor to determine if exist contact with the object in the work space of the prototype. The final position information of the motors is using ...
